Installation Guide
- Disconnect the fuel line from the existing carburetor and ensure the fuel valve is in the OFF position. Allow the engine to cool completely before proceeding.
- Remove the air intake cover and filter housing to access the carburetor mounting bolts. Keep all fasteners organized for reassembly.
- Disconnect the throttle linkage and choke cable from the old carburetor. Take note of their positions for correct reconnection.
- Unbolt the old carburetor from the intake manifold and carefully remove it. Inspect the mounting gasket and replace if damaged.
- Clean the intake manifold mating surface thoroughly to ensure a proper seal. Remove any old gasket material or debris.
- Position the new carburetor assembly onto the intake manifold with a new gasket. Hand-tighten the mounting bolts first, then torque evenly in a cross pattern.
- Reconnect the throttle linkage and choke cable to the new carburetor in their original positions. Verify smooth operation of both controls.
- Attach the fuel line securely to the carburetor inlet. Check that all clamps are tight and properly seated.
- Reinstall the air filter housing and intake cover. Ensure all connections are secure and properly aligned.
- Turn the fuel valve ON and check for any fuel leaks around connections. Address any leaks immediately before starting the engine.
- Prime the fuel system by squeezing the primer bulb until firm. Start the engine and allow it to warm up to operating temperature.
